DfMA and Complex Geometry: Making the Unbuildable Buildable
The Challenge of Complex Geometry
Ambitious architectural forms push the boundaries of what can be built. Doubly-curved facades, parametric structures, and organic forms require sophisticated rationalisation to become constructible. The gap between design intent and fabrication reality is where computational geometry thrives.
Geometry Rationalisation
Rationalisation is the process of simplifying complex geometry into buildable components while preserving design intent. This might mean approximating a freeform surface with planar panels, optimising a facade into repeatable module types, or decomposing a structure into elements that can be fabricated with standard equipment.
Design for Manufacture and Assembly (DfMA)
DfMA principles ensure that designs are optimised not just for appearance but for efficient manufacture and assembly. This includes reducing the number of unique components, standardising connection details, and designing for the specific capabilities of the fabrication shop that will produce the elements.
Fabrication Automation at Scale
Once geometry is rationalised, contractor-specific automation produces hundreds of fabrication drawings at 20-30x the speed of traditional methods. These systems include embedded quality assurance, automated dimensioning, and direct output to CNC and robotic fabrication equipment. The automation is reusable across the contractor's full portfolio of projects.
Sustainability Through Optimisation
Computational geometry enables embodied carbon reduction through material optimisation, solar performance analysis through facade studies, and waste reduction through rationalised panel layouts. By controlling variation and optimising material use, complex geometry projects can achieve sustainability outcomes that traditional approaches cannot.
